A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.20 in. Segment (2) is hollow with an outside diameter of 1.48 in. and a wall thickness of 0.14 in. If segment (2) has a normal stress of 20 ksi, determine the normal stress in segment (1).

KIN 6015 – Biomechanical and Neurological Basis of Human Movement   You were tasked by the PLNU Athletic Training Staff to measure the kinematics and kinetics of countermovement jumping of 15 women’s soccer players, 15 women’s volleyball players, and 15 women’s basketball players and now your research team is writing up the manuscript. Write the Methods section of this hypothetical completed study. Focus on the subjects, instrumentation, protocol, and analysis aspects of the study (i.e., motion analysis system, force plates, marker sets, subject movements, relevant dependent variables, research design, etc.). The team wishes to submit the paper to AJSM so details are key!

Before an automotive engine is started, its timing belt has a length of 43.00 in. and a temperature of 70°F. At the engine operating temperature of 210°F, it is determined that the belt has elongated to 43.04 in. What is the coefficient of thermal expansion of the belt?
